Highly chemoselective reduction of methyl 2- and 3-nitro-oxypropionate (9) and (12) with calcium borohydride was accomplished to give the desired 2- and 3-nitrooxypropanols (6 and 13) in good yields without affecting the nitrooxy group.
NO donors. Part 16: Investigations on structure–activity relationships of organic mononitrates reveal 2-nitrooxyethylammoniumnitrate as a high potent vasodilator
The vasoactive properties of 14 organic mononitrates were investigated in vitro using PGF(2 alpha)-precontracted porcine pulmonary arteries. A surprisingly wide range of vasorelaxant potencies was observed (pD(2): 3.36-7.50). Activities showed to be highly sensitive to the molecular structure and the substituents at the molecular carrier of the nitrate group. A correlation between lipophilicity and vasorelaxant potency could not be recognized. 2-Nitrooxyethylarmmoniumnitrate (1) was found to be slightly superior to the high potency trinitrate GTN.
